One reason for the restart of inactive B channels is to handle the case 
where the two endpoints have gotten out of sync. Every hour (or is it 
every two hours?) asterisk will do a restart on those channels which it 
considers idle at that time.

There are broken PRI implementations that reset and drop _all_ B channels 
and not just the signaled ones. The Panasonic PRI cards for the KX-TD1232 
lines for pbx:es for example.

There has been talk abount making the reseting configurable. Our solution 
has been to change the interval to 10 years.
